Today’s devices are increasingly required to stay connected, the Internet of Things (IoT) is starting to get crowded. Apart from smartphones, smartwatches and smart TVs, we are witnessing the advent of … smart cookers, smart ovens, smart refrigerators and many other (sometimes unnecessarily) smart things. According to Cisco estimates, the Internet of Things will contribute to nearly 50 billion smart items being part of everyday use by 2020. Gartner is much more cautious and states that the above estimate should be reduced by almost a half, i.e. to a total of 26 billion units.

We are another link in the chain of evolution: the homo cyberneticus.

Are we aware just how much data has changed our lives?

Social life

Do random people know more about you than your parents or relatives in general? That is the definition of the digital age. A few mouse clicks are enough to scan a piece of your life that you have voluntarily shared with the world.

But we have to remember the cost of digital exhibitionism. The knowledge of each one of us is at our fingertips, or rather the touch of a smartphone. No clairvoyant or internet analyst is needed here. Just a glimpse of anyone’s social media profile is enough (another reason why privacy settings are important).

Are you complaining about the lack of privacy or anonymity on the web? Remember that you renounced it voluntarily when you decided to participate online. Therefore, there is nothing to moan about. However, you should learn how to manage your data and rethink your content.

Work

Looking for a job or have an appointment? Take care of your wall first. HR specialists know that Big Data overexposure to social networking sites will tell them more. Employers might say: “He posted an inappropriate photo or comment or an entry about a former employer”, “He posted alcohol or other drug-related content”, “He demonstrated poor communication skills”. The conclusion is simple: Big Data is your online business card. Moderate your content. You are never sure if your online profile will not be visited by a HR headhunter from the company that you have always wanted to work with.

Online love

Thanks to Tinder, the app that is conquering the American dating market, some of us are even dating digitally. By using Big Data and analyzing cookies, Tinder tells us which of the users close to us might fancy us. Instead of believing in love at first sight, we prefer to first look at our potential date carefully. We swipe our fingers on the screens of our smartphones: either to the left or to the right. This is how we choose the people with whom we would like to go on a date. We use a zero-one approach. We can also define the parameters that our potential date should meet, i.e. select the data that we want. Thanks to Big Data we are able to choose dates that have all of our desired traits.

Someone may ask: what about the ‘first impression’, the thrill that accompanies the first face-to-face meeting if you can browse the web and find out everything about our potential date? On the other hand, online dating is meant for people who do not want to ‘buy a pig in a poke’ as opposed to the old school blind date. Additionally, a key question arises: can we make use of this data? Analysts would phrase the question differently: can we convert Big Data into Smart Data? Data opens a secure communication area for us, as long as we can use it.

The internet browser as a mirror

The web is personalizing. Apart from the ‘Internet of Things’, the concepts of ‘The Internet of Me’ or ‘Internet Online’ are emerging. The network learns our behaviours and adapts to them.

Show us your browser history, bookmarks etc. and we can tell you who you are. Show us the ads that pop up on the web and we will tell you what you are looking for and what you are interested in. Show us your history of recently opened pages and we will tell you what you will see in the coming days. Everything is targeted marketing.

How do we know this? Because your network traffic is stored in the form of cookies that contain anonymous information about you. They contain data on what you are looking for on the web, what you are interested in, what sites you visit and how much time you spend on them, what you bought recently, what you have in your shopping cart, etc. No worries — cookies do not contain any ‘sensitive data’, such as your name, address, etc. In all honesty, this kind of personal data is completely irrelevant to the analyst.

All they care about is ‘what you click’ and where. These are the cookies that advertisers are fighting over because they tell them what they should display on your computer screen. Your digital portrait is made with Big Data’s behavioural Engine. It is what determines what ads are displayed in your browser. Looking for a jacket for winter? A few hours later you get the ad for the jacket that you looked at when browsing stores. Have you looked for information about holidays in Spain? You will soon see an all-inclusive offer with a discount price in the corner of your screen. Contemporary advertising, called personalized or behavioural advertising, is the litmus test of your online activity. It lives with you and learns your behaviour.

If there were 10 identical computers and among them would be yours, it would take you a few minutes of browsing the web on each of them to figure out which one belongs to you. You could tell it was yours by the advertisements that would pop up on websites.

The digital world versus the analogue world

The boundary between the digital and analogue world is becoming blurred with each coming day. Life is digitizing at a dizzying pace and Big Data goes into every part of it. As estimated by Oracle, Big Data grows by about 4 percent annually, and the value of the Big Data market is growing six times faster than the entire IT industry.

The internet already contains 8 zettabytes of data, and by the year 2020, we will generate more than 45 ZB. The IDC calculates that more than 5.2 GB of data per capita will be shared per person and 1/3 of them will be of great value because they will be carefully tagged and analyzed by data researchers. The real challenges are still ahead of us. The future is Huge Data, says the president of the largest data warehouse in this part of Europe.

The companies that use Big Data today no longer focused on simply collecting, processing, segmenting and analyzing data, which is referred to as ‘data harvesting’, and then monetizing on it. Big Data is a digital guide that improves not only business but also everyday life. Forrester research shows that 5 percent of decision makers in companies (especially in the IT sector) admit that data analysts empower businesses to streamline their business decisions, including the use of data for ‘doing good deeds’, that is activities that bear the mark of corporate social responsibility. This increasingly popular trend is referred to as Good Data or using the broader term Big Data for social good. Anonymous behavioural data makes it possible to understand the behavioural patterns of larger groups of people and then use them to benefit society, social impact data.

Of course, we must remember that Big Data doesn’t provide black and white answers. Big Data doesn’t think for us, but it expands our thinking and allows us to venture into areas previously inaccessible. Big Data provides a bigger picture, an overview of each case with virtually unlimited perspectives. Therefore, there is no exaggeration in claiming that Big Data today’s ‘digital God’.
